ABSTRACT:
A polytetrafluoroethylene mixed powder, which is obtained by mixing low molecular weight polytetrafluoroetylene powder and high molecular weight polytetrafluoroethylene powder obtained by emulsion polymerization of tetrafluoroethylene, wherein the low molecular weight polytetrafluoroetylene powder has a number average molecular weight of 1,000,000±500,000 and a maximum peak temperature of 327±5° C. in the endothermic curve appearing on the crystalline melting curve obtained by using a differential scanning calorimeter, the high molecular weight polytetrafluoroetylene powder has a number average molecular weight of 4,500,000±1,000,000 and a maximum peak temperature of 340±7° C. in the endothermic curve appearing on the crystalline melting curve obtained by using a differential scanning calorimeter, and the mixed powder has evident peak temperatures of 327±5° C. and 340±7° C. in the endothermic curve appearing on the crystalline melting curve obtained by using a differential scanning calorimeter.
